In this video, I will talk about code p2048 testing and replacing Cummins 6.7 def injector. I received the "Service DEF System See Dealer" message on my instrument cluster. I was annoyed, but continued about my day of driving. Then, I received the DREADED "Reduced to 5MPH in 150 miles See Dealer" message, that got my attention REAL QUICK! Upon further research, code p2048 was stored. This points to an issue with the DEF injector circuit. I will go through the DEF injector tests and show how replacing the DEF injector can solve your issue.

My husband has a 3500 Ram. DEF problems mostly because he forgot to reload. Counting down the miles until he need to creep along at 5 mph. Went online and bought a new filter. Took it to a garage and they took the old one out and put in the new. Took it to a local Dodge dealer to reset the system. They couldn't do it. He ran out of miles on the way home. Pulled into a neighbor's driveway and decided he could make it home quicker if he drove in REVERSE because it ran at full speed backwards. Fortunately, we live in a very rural area, so it was possible for him to do that. However, he only went a couple of hundred feed backwards and then decided to turn around again. Drove it a few feet at 5 mph, the message changed and in an instant was running at full speed in DRIVE. It reset itself. We would suggest finding an empty parking lot, driving around backward for several hundred feet, turning around and then driving in forward gear. It might have just been a Christmas miracle; but all we know is that it's fixed and running like a top. Who knew?

@JouppiOutdoors 7 месяцев назад

That’s a crazy story! Thanks for sharing!

@HeyWatchMeGo 6 месяцев назад

@debfleming5871 Did the code show up again, or did the 'fix' stayed fixed? T.I.A.

@JouppiOutdoors 6 месяцев назад

Stayed fixed, I was pretty confident when the injector had no continuity that it was definitely the issue.

@jakethesnake9528 2 месяца назад

Amazing. I know it has been a while, since the reset. Have y'all had problems or codes pop up with the DEF system?

@stephennadaud8416 10 месяцев назад

Every step was nicely explained. Particularly with disconnecting those connectors. It's great for me to know how without breaking them.

Thank you I just got the service def see dealer on Sat and by Monday morning I had the 5 mph after 150m message. I just replaced the def injector ($500 at the dealer) and now the 150 mile countdown is gone and now after driving and starting it up twice the check engine light is gone as well. Thank you so much for the video!

I recently removed my DEF injector and cleaned the white crystals out with hot water. My 3500 had only 51k on it and was surprised how dirty it was. I also replaced the 10 mm bolts with stainless steel.

@jessejames8843 6 месяцев назад

Also if I replace the def injector will it keep it from going into limp mode or do the codes need to be removed by the dealership, thanks in advance

@JouppiOutdoors 6 месяцев назад

T.u. for the comprehesive vid. Do u have any idea the location for the def pressure/ temperature sensor.

@JouppiOutdoors 7 месяцев назад

You’re welcome, I believe that sensor is located in the def tank itself.

@jasonconnors8644 10 месяцев назад

You also will start seeing def coming out your exhaust pipe, white crystals , if you start seeing this it’s your def injector

@JouppiOutdoors 10 месяцев назад

@hazardouslo318 10 месяцев назад

Yeah remove it and clean it with warm water the def has white crystals then put new bolts because they get really rusty also don’t fill your def to full because it gets clogged more happened to me

@JouppiOutdoors 10 месяцев назад

Not a bad idea given how easy it is to remove.

My 2014 Ram 2500 4WD. Same issue . I threw a new def injector and still had the same results . Both nozzles had the same Ohm reading. I found out during my Drag link recall service there was an update/recall notice for the Def system. After the Flash . Code is gone and running great . No Charge. I hope This helps.

Hey my bolts on my 2013 are completely done. I cant get them out.. do you have any solutions?

@JouppiOutdoors 7 месяцев назад

The best info I could offer would be to soak them in PB Blaster and use a little heat when trying to break them loose.

@klforrest573 5 месяцев назад

Do you fill your DEF up at the pump or fill from the box? I attempted to fill from the truck stop DEF pump one time & the whole nozzle was crystallized & nasty as heck - there was no way I was going to stick That in my tank. Since the first tank fill up, I’ve used the box - so far no issues within the system.

@JouppiOutdoors 5 месяцев назад

99% DEF from the box, occasionally from the pump. The failure was electrical so not a result of the type of DEF in this case.

@user-mq1sx4jq7y 9 месяцев назад

I just got the def message. Code U02A2 remember. P CODES= Power train(actual parts needed). U codes = wiring and network communucations (possible baf wires)

@thebigd6249 4 месяца назад

What’s the update to your other codes. Did the battery swap rectify that? Also, would antiseize be a good idea for those two 10mm bolts? Great video. That looks really easy.

Unfortunately the other code ended up becoming a failed turbo actuator. Anti seize would be an excellent idea!

@jameskrause3553 25 дней назад

Do you meter on ohms or what

@JouppiOutdoors 25 дней назад

Yes, set the meter to ohms and check the continuity between the pins. If no continuity, the injector is bad.

@cwilks5592 8 месяцев назад

I started using the Peak Platinum in my Cummins about 8 months ago. My average between regeneration was in the low 300s. I refill at half tank, as the peak regular has been diluted/replaced by the platinum my miles between regen have been going up. Last time I was 551 between, my last regen was 632, not towing. I’ve been watching it because I was concerned that my Pedal Commander would make it regen more. It hasn’t. On a side note, the pedal commander has made an enormous drivability improvement.

@JouppiOutdoors 8 месяцев назад

Thanks for the info on the pedal commander. Just did the turbo actuator a few weeks ago…..not hard to do but ooof….pricey!

@cwilks5592 8 месяцев назад

@@JouppiOutdoors Not sure what your miles are but Ram extended the actuator warranty. I’d have to look at my paperwork but it’s well past 100k miles.

@SubjectivelyDan 2 месяца назад

Kinda weird that using a different def changed the miles between regens since the def injector is downstream from the dpf in the tube leading to the scr so shouldn't make any difference. Did you change anything else at the same time?

@cwilks5592 2 месяца назад

@@SubjectivelyDan Good point, no other changes at that time. I don’t know what else to attribute it to, but yeah, it doesn’t do anything to the DPF. driving characteristics hadn’t changed. I don’t remember when I started using hotshot EDT, Could that have made any difference.
